Rav Yair Kahn Issur Melakha Erev Pesach The gemara at the beginning of Pesachim has a lengthy discussion attempting to interpret the term "or." Inter alia, the gemara (2b) quotes a beraita regarding the prohibition of work on Erev Pesach: "From when on is work prohibited on the fourteenth (Erev Pesach)? R. Eliezer ben Yaakov says from the time of 'or,' R. Yehuda says from sunrise." Masekhtot - Iyun

Rav Yair Kahn Daf 22a - The Dispute Between R’ Meir & R’ Elazar The Gemara (daf 22b) ascribes the dispute here to the dispute between Rabbi Elazar and Rabbi Meir as to which set of witnesses effectuate the transaction intended by a document - the eidei mesirah (“witnesses of delivery” who witness the physical transfer of the get between the two parties) or the eidei chatima (“witnesses of signing” who sign the document): Masekhtot - Iyun
Rav Yair Kahn Lo Chazra Shelichut etzel Ha-baal (24a) The Gemara in our passage assumes, as a simple matter, that shelichut where an agent cannot return to the sender is invalid. This is why a woman cannot be both her husband’s delivering agent (sheliach holakha) and her own receiving agent (sheliach kabbala). Masekhtot - Iyun
Rav Yair Kahn Rei’ach Ha-get — Scent of Divorce (24a-25a) Our Mishna brings a number of examples of gittin which are invalid because they are not “lishma,” “for her name,” a requirement derived from the term “lah,” “for her,” which the Torah uses in the context of divorce. Masekhtot - Iyun

Rav Yair Kahn Bereira Continued (25a-26a) In the previous shiur, we explained that even though a stipulation may be based on something which will happen in the future, this stipulation is not dependent on the law of bereira. This is because the law of bereira is only relevant when a characteristic element is missing from the act or the effectuation, while a stipulation is dependent on an external factor. Masekhtot - Iyun
Rav Yair Kahn The Tofes of the Get (26a-26b) Our passage indicates, apparently, that the rules of writing a get are relevant only to the toref, the toref, the personalized essence, not the tofes (“typos” in Greek), the standardized part. Masekhtot - Iyun
Rav Yair Kahn Gittin 28b – One Who Has Been Led Out to Execution Regarding one who has been led out to execution, who according to the Mishna, we only suspect that in fact he has been killed, but we do not assume this with certainty ... Masekhtot - Iyun
